8.2
A simplified circuit for an analog input is shown in
Figure 8-3. Since the analog input pins share their con-
nection with a digital input, they have reverse biased
ESD protection diodes to V
input, therefore, must be between V
input voltage deviates from this range by more than
0.6V in either direction, one of the diodes is forward
biased and a latch-up may occur.
A maximum source impedance of 10 k
mended for the analog sources. Also, any external
component connected to an analog input pin, such as
a capacitor or a Zener diode, should have very little
leakage current to minimize inaccuracies introduced.
